No, the Final Act was the final season of Inuyasha. It ends where the komik jepang ends, so unfortunately not unless Rumiko Takahashi decides to pick up on the story again and writes a new series, but that I doubt will ever happen :(
No,it won't.Takahashi sensei clearly berkata inuyasha series had ended when the final act came out.Besides,she is drawing Kyoukai no Rinne now.But it still have chance to see Inuyasha's OVA again if jepang held activity like'It's Rumic World'.But i bet it spends many years to wait.
i doubt the final act is the final act after all so no lebih inu :( so unless u go to the studio and ask him to make some lebih episodes with inu and kagome's kids tht would be great! :D
